Summary: This study investigated the osmolality and osmoregulatory mechanisms of Solenaia oleivora under high salinity stress. The results showed that S. oleivora is an osmoconformer, and changes in inorganic ions, FAA, NKA, and gill structure play an important role in its osmoregulation.

Summary: The study found that the specific ion effects of Na+ and K+ were different on the growth of Ulva lactuca. Ulva lactuca showed better growth with high concentrations of NaCl, while KCl might have adverse effects on photosynthesis and cell wall. Transcription of PM H+-ATPase was induced specifically by high concentrations of Na+, while the induction of PM-Na+/K+-ATPase-like alone could not improve the growth of KCl-treated Ulva lactuca.

Summary: This investigation examines the kinetic characteristics and effect of acclimation to a brackish medium on gill V(H+)-ATPase activity in two hololimnetic populations of M. amazonicum. The study also investigates the cellular immunolocalization of the enzyme. The findings demonstrate the distribution of V(H+)-ATPase c-subunit in shrimps' pillar cells in fresh water and its absence after acclimation to a brackish medium. The importance of crustacean V(H+)-ATPase for ion uptake in fresh water is highlighted.

Summary: There are significant differences in Na,K-ATPase activity among different tissues in roach. The number of Na,K-ATPase alpha-subunits is strongly correlated with the activity. Cold acclimation increases the number of alpha-subunits in the heart, kidney and brain, but does not increase Na,K-ATPase activity. In the gills, the alpha-subunits do not change during cold acclimation, but Na,K-ATPase activity is depressed. Tissue-specific differences in Na,K-ATPase activity are not only determined by the density of alpha-subunits, but also affected by other factors.

Summary: This study analyzed the function of Na+/K+-ATPase in the response of Neoporphyra haitanensis to salt stress and found that it played a crucial role in maintaining the K+/Na+ homeostasis in the algae. The inhibitor ouabain caused Na+ accumulation and K+ leakage in the cells, disrupting the K+/Na+ balance and leading to decreased photosynthesis and oxidative damage in the algae.

Summary: This study explored the gill developmental mechanism of high larval mortality in Paramisgurnus dabryanus. The results showed that external gills appeared 12 hours after hatching and the number of external branchial filaments greatly increased at 2 days after hatching. Internal branchial filament primordial was formed at 5 days after hatching and by 9 days after hatching, external branchial filaments were not observed outside. Gill filament and lamellae increased significantly in number and length from 15 days after hatching. The specific activities of Na+/K+-ATPase steadily increased until 12 days after hatching and then slightly decreased. Abundant gill lamellae were observed at 40 days after hatching. The sensitive period of larval and juvenile P. dabryanus development was from 6 to 15 days after hatching.

Summary: This study cloned and confirmed ORF sequences of ion-transportation-related genes in Kuruma shrimp, analyzed their tissue expression patterns, and assessed their mRNA expression levels during exposure to different salinity levels. The results suggest that these genes play critical roles in the adaptation of aquatic crustaceans to changes in environmental salinity.

Summary: Life in freshwater poses osmotic and energetic challenges for organisms, particularly arthropods. The mechanisms of ion uptake from freshwater environments are still poorly understood, but the proton pump V-type H+ ATPase (VHA) and the Na+/H+ antiporter (NHA) have been proposed as potential models. This study explores the evidence for these models in crustaceans, insects, and teleost fish and emphasizes the need for further research on ion uptake mechanisms in freshwater habitats.

Summary: Phenotypic divergence is a key characteristic of adaptive radiation. This study examined the differentiation in ion regulation characteristics among populations of prickly sculpin (Cottus asper) from different habitat types and explored the relationship between environmental water chemistry and physiological characteristics. The results suggest that habitat variation may play an important role in driving differences in gill Na+/K+-ATPase and H+-ATPase activity across populations, and the combined effect of water Na+ and pH may have contributed to physiological adaptation during freshwater colonization and dispersal of C. asper after the last glacial period.

Summary: This study investigated the regulation of gill (Na+, K+)-ATPase activity in freshwater crustaceans, finding that protein kinases A and C, as well as FXYD2 peptide, play a role in modulating enzyme activity through phosphorylation mechanisms instead of through the expression of different isoforms.

Summary: This study used the gill (Na+, K+)-ATPase as a molecular marker to analyze the effects of Co2+ on K+-phosphatase activity in the Blue crab Callinectes danae. The results showed that Co2+ can either stimulate or inhibit K+-phosphatase activity, and it has a higher affinity for the enzyme compared to Mg2+. The findings contribute to our understanding of the mechanism of action of Co2+ on crustacean gill (Na+, K+)-ATPase.

Summary: Freshwater turtles of the genera Trachemys and Chrysemys can survive total oxygen deprivation for long periods of time, with the gasotransmitters nitric oxide (NO) and hydrogen sulfide (H2S) playing central roles in regulating their physiological responses. These signaling molecules interact with protein thiols to modulate metabolic suppression and protect against oxidative damage, highlighting their importance in the remarkable tolerance of freshwater turtles to oxygen deprivation.

Summary: Gulf toadfish with aglomerular kidney can survive in various salinities including high Mg2+ environments. The study found that transcriptional regulation of renal Mg2+ transporters is influenced by a combination of elevated Mg2+ levels and salinity, rather than high Mg2+ levels alone.
